TFS Series Snap-Acting Switches

C&K's TFS series snap-acting switch comes in two models. One has .020 by .187 quick connect terminals, and the other has molded-in wire terminals. Both are sealed to IP ratings. Ideal for price-sensitive applications, the rugged and reliable TFS series provides an operating life of up to 100,000 cycles.

The quick connect series is designated IP40 and the lead wire series is IP67. Sealing makes it a viable solution for protection against dust particles or fluids, including perspiration and water. The highly reliable miniature snap-acting switch provides an economical option for price-competitive applications that require high performance and quality.

The RoHS-compliant TFS series subminiature switch features a footprint of only 10.30 mm x 33 mm with a height of 16.10 mm, including the actuator. The TFS series switches feature a maximum actuator operating force of up to 200 grams and a minimum release force as low as 10 grams.

Available in a number of circuitry configurations including SPDT (single pole, double throw), SPST NO (single pole, single throw, normally open), and SPST NC (single pole, single throw, normally closed). The durable miniature switch series is constructed with a 94VO plastic actuator, cover, and base with silver alloy movable contacts. The TFS also has the option for a stainless steel lever. The TFS series switch features a contact rating of up to 10 A and a voltage range of 125 V_AC to 250 V_AC. The operating temperature ranges from -40°C to +85°C.
