Mechanical single position limit switches

Available in: 134 versions

In mechanical single position limit switches without positive opening, a telescoping plunger executes the switching process. With its help, a mechanical switching element is connected in a separate, sealed chamber. The optimal choice of the plunger shape in combination with our cams is decisive in individual cases. This guarantees a long service life for your application.
