TZ Limit Switch
- Features
♦ Double circuit type of limit switch
♦ Highly rigid construction , consists of intensive plastic and aluminum cast (Head and cover snugly fit in box)
♦ Small volume , water-proof and oil-proof construction
♦ Built-in basic switch with double spring mechanism, longer mechanical life
♦ Smooth operation with greater OT
♦ Easy-to-wire circuit opening design
♦ Wide varity of actuators, easily use
