The next generation in 22-mm XW switches from Idec features a smooth, ridgeless button, designed to prevent dust build-up and ensure comfortable operation, which reduces user fatigue and stress, the company says. Ideal for food and beverage applications, as well as food processing equipment, this design enables quick and easy cleaning. Each operator features both push-turn and push-pull action. The potential energy level of the latched status is lower than that of the normal status. This is known as a reverse energy structure. It means that if the switch is damaged, the NC contacts will turn off, thus stopping the machine.
