ITW's engineers have put some thinking into this issue and come up with the 49 series switch. This switch series is rugged, panel sealed, available with round or square bezels and LED lighted or non-lighted. Bushing mount or snap-in mounting is also available.
Series 49 switches are ideal for demanding applications in harsh environmentswhere water, moisture or dust is problematic as they are panel sealed to IP67. ESD protection is 15KV minimum and the gold contacts ensure reliable switching over a long life of up to 1 million cycles.
