The VX-56-1A3 is a miniature basic switch designed for high contact reliability with a low operating force. This model is equipped with a hinge roller lever actuator and requires a maximum operating force of 0.29 N. Key operational characteristics include a maximum pretravel of 4.0 mm, a minimum overtravel of 1.6 mm, and an operating position of 20.7 ± 1.2 mm. Featuring an SPDT contact configuration and solder terminals, its construction includes a stainless-steel lever and a polyacetal resin roller. Due to its unique internal mechanism and low force requirement, it is well-suited for applications involving the detection of lightweight objects.
