Safety Switches & Guard Locking
Safety switches and guard-locking components monitor access to industrial machinery. Select the device by its locking principle, actuator, contact arrangement or communication interface, and the installation requirements of the complete safety function. Power-to-lock and power-to-unlock executions behave differently when power is lost. Position switches, coded actuators and locking devices also have distinct roles. For replacement enquiries, provide the full manufacturer order code, existing switch and actuator references, circuit details and installation photographs. Component capabilities must be applied within the machine risk assessment and validated safety design. Browse model-specific technical data and request the required switches, mating actuators and accessories from Seven Star LLC.

Frequently Asked Questions
What is the difference between power-to-lock and power-to-unlock guard locking?
A power-to-unlock device stays locked by spring force and needs voltage to release, so the guard stays locked if power is lost. A power-to-lock device needs voltage to hold the guard and releases when power is removed. The choice follows the risk assessment of the machine.
Why does the actuator matter?
A safety switch and its actuator work as a pair. Straight, angled, hinged and coded actuators are not interchangeable between series, so the actuator is ordered by its own reference.
What is a transponder-coded safety switch?
It detects a coded electronic actuator without mechanical contact. Coding levels differ between versions, which affects how easily the device can be defeated with a spare actuator.
Can one switch reach a required performance level on its own?
The performance level belongs to the complete safety function: the switch, the wiring, the evaluation unit and the output devices. The switch data are one input to that calculation.
What should I send for a quotation?
Send the complete order code, the actuator reference, the solenoid voltage, the connection type and the quantity. For a replacement, include a photo of the nameplate.
