30 mm key switches

30 mm key switches give a larger key cylinder and bezel for heavy machinery and 30 mm panel layouts. Jinhong offers a plastic-head and a stainless-head version.

Jinhong 30 mm key switch series
Series	Head	Rating	Protection	Approvals
SD30	Plastic	10 A, Ui 600 V	IP65	UL, CE
SS30	Stainless steel	10 A, 250 V AC	IP40	UL, CE

Both come in 2- and 3-position maintained versions with standard or short contact blocks. Choose SD30 where IP65 sealing is needed; SS30 where a metal-look head matters more.

Matching 30 mm devices: push buttons and selector switches. Back to all key switches.

Typical uses: maintenance and setup modes, machine enable, and locking out operation on machine tools, transport and medical equipment.
