What are the different uses for WLNJ Limit Switches and WLNJ-30 Limit Switches?

WLNJ:

Because the coil spring is a single wire, the rod flexes considerably. Use WLNJ when the arrival position of the sensing object fluctuates.
The flexibility of the rod, however, causes gaps to appear in the coil spring. These gaps may cause foreign matter to be caught or accumulate.

WLNJ-30:

The coil spring consists of three tightly wrapped wires, so there is almost no flexibility in the rod. Also, no gaps form in the coil spring.
