LD Safety Switch

A safety switch turns off when the front cover or the right door is opened. As a result, the relay on the PSU
cuts off the power supply (+5V) to the four LD boards. (The electric circuits go through the EGB and IOB.)
The LD safety switch system stops the laser beam when the cover is open.
