Amendment February 16, 1982 The scope of claims for utility model registration is amended as follows. ■Utility Model Registration Claims In a proximity switch that has an oscillation circuit consisting of a tank circuit including a detection coil and an amplifier circuit that amplifies and feeds back the voltage generated by this circuit, a bypass filter is provided between the tank circuit and the amplifier circuit. A proximity switch characterized by being interposed. The brief description of the drawing has been amended as follows. ``High-pass filter'' in lines 12, 13, and 15 of page 5 of the specification box has been corrected to ``bypass filter.'' Page 5, lines 10-11 of the specification, "Electrical circuit diagram of the proximity switch" was corrected to "Electrical circuit diagram of the oscillation circuit of the proximity switch." On page 5, line 11 of the specification, "Fig. 2 is a block diagram" was corrected to "Fig. 2 is a block diagram of a proximity switch." ``Oscillation circuit'' on page 5, line 14 of the specification cylinder has been corrected to ``1 tank circuit.'' On page 5, line 16 of the specification, "switch operation circuit" was corrected to "1 amplifier circuit".

Claims

[Scope of utility model registration request]

A proximity switch that is equipped with an oscillation circuit that includes a detection coil, and a switch operation circuit that regulates load energization on and off based on the oscillation output, with a high-pass filter interposed between both circuits.
