Why Choose This Push Button Switch?

This panel mount push button switch brings professional-grade durability into settings that don’t require complex controls or high-end industrial gear. Whether you’re building a custom control box, retrofitting a device, or simply replacing a worn out button, this switch offers:

• A single-pole, single-throw design that’s easy to wire and understand.
• A 3A at 125VAC rating that gives you headroom for many projects rather than just minimal switching load.
• A panel-mount form factor with threaded bushing for a tight, secure fit in enclosures and front panels.

Installation Tips & Everyday Use

When installing this switch, make sure to cut a panel hole around 6.35 mm (¼-in) diameter, secure the switch with its threaded bushing and nut, and connect the wire-lug terminals using appropriate gauge wiring (for example 18–22 AWG is typical for 3 A loads). Since it’s momentary (ON only while pressed), it’s perfect for functions like reset buttons, start triggers, or user-input switches — not latching ON/OFF toggles.
