Claims

[Scope of utility model registration request]

A timer comprising an operational amplifier, a variable resistor connected between the inverting input terminal of the operational amplifier and a switch of the charging section, and a capacitor connected between the inverting input terminal and the output terminal of the operational amplifier. A setting section, a comparator section having an operational amplifier that inputs the output voltage of this time-limited setting section and a reference voltage setting means, a transistor that is turned on and off depending on the presence or absence of the output voltage from this comparator section, and an auxiliary device connected to this transistor. A timer comprising: a relay drive section having a relay;
