Microswitch and Powerswitch
Microswitch
The microswitch notifies the timer that the clamping lever is down. A failed microswitch may cause one of the following two adverse affects.
1) The heating will not start. 2) Even after the contact points is fused, malfunctioned microswitch would cause the power to keep distributing , resulting in a persistent heating state.
The new microswitch has been used since 1994, replacing the old one for easy changeover and minimum risk of allowing accidental Switch-On by hand or some other causes even with the clamping lever in OFF position.
Power Switch
When the machine is over-used and the timer is over-loaded, the heating time could get longer than pre-set time. Starting from 1994, we have adopted power switch with overheat-protection feature that shuts off the circuit.
