Claims

[Scope of utility model registration request]

In the push plunger type limit switch, the inner plunger linearly moves via a spring when the outer plunger provided at the upper part of the housing is pressed by an external force to operate the switch body built in the lower part of the housing. The inner plunger is configured such that the stroke of the linear movement of the inner plunger that operates the internal operating mechanism of the switch body is suitably smaller than the entire operating stroke including the over-permissible operating stroke of the internal operating mechanism of the switch body. A limit switch comprising a means for restricting the linear movement of the plunger.
