Safety Interlock Switches – STP Twin Design Type 2 Safety Switches

Safety Interlock Switches
STP Twin Design Type 2 Safety Switches

EUCHNER Design Type 2 Safety Switches are used to protect personnel by monitoring and interrupting the safety circuit depending on the position of the machine guard. The locking solenoid holds the guard closed until a stored energy hazard has passed. It can also prevent damage to a part in process due to an inadvertent machine shutdown. To meet current worldwide standards, safety interlock components cannot be easily bypassed. These switches have positive opening contacts and redundancy to guarantee that they fail to a safe state. The STP Twin safety switch is installed where in the past two safety switches were necessary. The double head enables two safety guards to be protected using only one switch.
