Abstract

The utility model relates to an operation tester for plug sockets and electric appliance switches. A connecting rod mechanism is driven by the rotation of a motor to drive an upper table to move up and down repeatedly in a straight line, and a socket and a plug to be tested, which are respectively clamped and fixed on the upper table and a lower table, are plugged into each other and pulled out from each other synchronously. When one operation of plugging in and pulling out is completed, voltage signals of the plug and the socket are conveyed to a circuit part for being counted and displayed. When a count value reaches a presetting value, a plugging in and pulling out test is stopped. Consequently, the purposes of automatically plugging in and pulling out plugs and sockets and displaying plugging in and pulling times are reached.
