Title:
TWO-WIRE PROXIMITY SWITCH AND GAME MACHINE
Document Type and Number:
Japanese Patent JP2005174731
Kind Code:
A
Abstract:
To provide a two-wire proximity switch that can be used even in an environment wherein static electricity of excessive wave height is repeatedly inputted, and prevent the reduction of operating time due to the evasion of failure and maintenance.
With respect to the two-wire proximity switch comprising a coil to which a detected body approaches, a detection circuit for detecting the approach connected to the coil, and two output sections that make the detection circuit connectable to the outside, the end part of the coil and the output sections are connected by a surge protection means protecting the detection circuit from a surge.
