Multicomp Pro Snap Action Micro Switch, Pin Plunger, SPST-NC, 3A, 125V AC

The Multicomp Pro Snap Action Micro Switch is a miniature SPST-NC switch with a pin plunger actuator, rated for a maximum contact current of 3A at 125V AC. It is suited to low-power control circuits and signal switching.

Overview

This micro switch is designed for miniature applications and delivers consistent performance in compact layouts. As a single pole single throw normally closed (SPST-NC) device, it provides a crisp, tactile response with an operating force of up to 90gf, making it well suited to applications that require precise actuation. The pin plunger actuator supports accurate and repeatable switching action.

Key Features

• Normally closed (SPST-NC) contact configuration for fail-safe operation
• Pin plunger actuator for accurate and repeatable switching
• Miniature type with a compact form factor for tight spaces
• PC pin terminals for secure soldering onto printed circuit boards
• Maximum contact current of 3A with a nominal contact voltage of 125V AC
• Operating force of up to 90gf for responsive actuation

Electrical and Physical Characteristics

The switch offers a contact resistance of 100mΩ and an insulation resistance of 100MΩ, supporting reliable conductivity and safe operation. The compact design measures 43 mm in height, 33 mm in width and 15 mm in depth, and weighs 0.646 g, allowing easy integration into space-constrained layouts.

Choose the Multicomp Pro Snap Action Micro Switch for control circuits and signal switching where a compact, normally closed switch with a precise pin plunger actuator is required.
