DS663 Descripción general
A pushbutton switch is an electromechanical control component that changes a circuit when an operator presses or releases its actuator. In the DS663, the SPST designation indicates a single-pole, single-throw contact arrangement, while OFF-ON describes the panel marking or operating sequence rather than necessarily proving whether the contact is momentary or maintained. The DS-663 series listings identify a 15 mm cutout and one normally open contact, so engineers should confirm the exact terminal and actuator configuration from the ordered suffix before production release.
Verified listings provide several important ratings, including 3 A at 125 VAC, 500 V DC, 125 VAC, and a 1 A/125 VAC variant description. Other source records report insulation resistance up to 100 megohms at DC 500 V, insulation withstand of AC 1000 V for one minute, and contact resistance below 20 megohms. Because the retrieved records refer to multiple DS-663 suffix variants, ratings should be matched to the exact manufacturer part number rather than generalized across the family.
Typical uses include panel power selection, test-equipment controls, small industrial control panels, appliance interfaces, and low-voltage control circuits. The 15 mm panel cutout supports compact front-panel installation, while the SPST contact structure simplifies wiring. A mechanically robust actuator and clearly marked OFF-ON position improve usability in equipment housings, although the enclosure, actuation force, terminal spacing, and environmental ratings are not provided in the retrieved data.
The primary design consideration is selecting the exact DS-663 suffix for the required contact action, terminal arrangement, panel hardware, and current rating. The related DS-663-C-R-W-PC-K-K listing is described as SPST-NO, OFF-(ON), 1 A/125 VAC, whereas another source describes the DS663 family as SPST, OFF-ON, 3 A/125 VAC. These differences must be resolved before treating any related variant as a drop-in replacement.
This page consolidates distributor listings, electrical descriptions, panel-mount dimensions, and cautious substitution guidance for engineers evaluating DS663. It distinguishes the target DS663 designation from longer DS-663 suffix variants and highlights the missing mechanical and lifecycle information rather than inferring unsupported specifications.

Aplicaciones típicas
DS663 es adecuado para 6 aplicacións: Industrial Control Panel, Test Equipment Power Selection, Appliance User Interface, Small Control Signal Interface, Control Panel Demonstration Unit, Compact Equipment Enclosure.
Industrial Control Panel
The DS663 can provide a simple user-operated control input for an industrial enclosure when the exact suffix matches the required OFF-ON behavior. Its listed SPST format simplifies panel wiring, while the 15 mm cutout supports compact front-panel mounting. For a control-signal application, the stated 3 A/125 VAC contact rating provides substantial capacity, but the designer should still verify the exact suffix, contact action, actuator travel, and terminal spacing.
Recomendado
Test Equipment Power Selection
DS663 is suitable as a front-panel power-selection or function-control switch for compact test equipment. The red actuator listed for the related DS-663 series provides a recognizable operator interface, and the SPST contact arrangement can switch a control input without complex logic. The listed 3 A/125 VAC rating should be checked against the load, especially when inrush current or inductive behavior is present.
Recomendado
Appliance User Interface
The DS663 can be used as a panel-mounted user control in appliances or light industrial products where a mechanical OFF-ON input is preferred. Its 15 mm related-series cutout and red actuator support a compact front-panel layout, while the SPST contact reduces wiring complexity. Confirm whether the exact device is maintained or momentary before finalizing the mechanical design, and verify the enclosure clearance around the actuator.
Recomendado
Small Control Signal Interface
DS663 can be used for a low-voltage control-signal interface because the supplied data identifies a single SPST contact and an OFF-ON operating designation. The 3 A/125 VAC listing is well above many logic-level control requirements, but contact resistance and insulation values should be assessed against the system. Exact terminal numbering and whether the contact is normally open must be confirmed for the ordered suffix.
Recomendado
Control Panel Demonstration Unit
The DS663 is appropriate for education, prototyping, and demonstration panels requiring a clear mechanical input device. The panel-mount format and listed 15 mm cutout simplify integration into an enclosure, while the SPST arrangement is easy to wire for simple control experiments. Because the retrieved records contain inconsistent suffix-level ratings, prototypes should identify the complete part number and be checked against the manufacturer documentation.
Recomendado
Compact Equipment Enclosure
DS663 can serve as an operator input in a compact equipment enclosure requiring a discrete mechanical selector. The related 15 mm cutout helps constrain panel real estate, while the red actuator can improve visual identification of the control position. Before layout release, verify body dimensions behind the panel, nut or bushing requirements, actuator projection, terminal orientation, and the exact electrical state of the DS663 suffix.

Notas de diseño
Do not treat every DS-663 suffix as electrically identical. The retrieved records show a broader DS663 description of SPST, OFF-ON, 3 A/125 VAC, while a related DS-663-C-R-W-PC-K-K listing is described as SPST-NO, OFF-(ON), 1 A/125 VAC. Confirm the complete suffix and manufacturer datasheet before using a related part as a substitute.
Design the front panel around the stated 15 mm cutout for the related DS-663 listings, but verify the exact suffix drawing before machining. Also check actuator clearance, panel thickness, mounting hardware, rear-body clearance, and terminal orientation. A panel fit alone does not establish terminal compatibility or safe access to the connection.
Use the stated 3 A/125 VAC rating only after confirming it applies to the exact ordered configuration. For inductive, motor, capacitive, or high-inrush loads, add appropriate suppression and account for contact derating. The related 1 A/125 VAC listing demonstrates that current capability can vary across suffixes.
