C & K Tactile Switch, Surface Mount, 1.9 mm Actuator Length, SPST 50mA 32V dc IP40

C & K KMR231G LFS Tactile Switch is a high-quality surface mount switch featuring a 1.9 mm tactile actuator for precise momentary switching performance. This subminiature switch is designed for applications requiring compact size and reliable contact operation, with a single-pole single-throw (SPST) configuration.

The switch measures 4.2 mm in length and 2.6 mm in width, making it suitable for high-density printed circuit board (PCB) designs. It supports a contact DC voltage of 32 V dc and a contact current rating of 50 mA, capable of handling low power electronic control circuits efficiently.

With an IP40 rating, the switch offers basic protection against solid objects larger than 1 mm, and it is ideal for indoor and controlled environmental conditions. Silver contacts ensure excellent electrical conductivity and corrosion resistance, enhancing the switch's operational reliability over its 150,000 operation mechanical life span.

The switch operates within a temperature range of -40°C to +85°C and requires an operating force of 3 Newton, offering a tactile response suitable for user input interfaces. This component mounts easily onto PCBs using surface mount technology and features through-hole terminals to ensure a firm mechanical and electrical connection.

This product complies with the RoHS directive, making it environmentally friendly and free of hazardous substances. It is available in two activation strengths, 3N and 4N, with the IP40 model ensuring a good balance between protection and size.

Common applications include telephony devices, automotive electronics, and computer peripherals where compact, reliable, and tactile user feedback is needed. The switch features a compact 4.2 mm length and 2.6 mm width for high-density circuits.

It operates with a contact DC voltage of up to 32 V dc and contact current of 50 mA. Designed to meet IP40 protection rating, suitable for various environmental conditions. Materials include silver contacts for consistent conductivity and durability.

The operating force is 3 Newton, with a mechanical life expectancy of 150,000 operations. The switch supports a temperature range from -40°C to +85°C. Mounting style is surface mount with through hole terminals for secure PCB integration.

Complies with RoHS directive, ensuring lead-free and environmentally compliant construction. Applications include telephony, automotive systems, and computer peripherals.
