Switch and button [Type K64]

The K64 is produced to be highly durable and is therefore is particularly trusted for mining use. Beyond the large selection of standard switches, upon request we will gladly provide you with individualised switches to meet your requirements. To signalise switch conditions, the K64 can be combined with our own installed LED solutions, the LD1 and LD3.
