Compactness:
Robustness: Stainless shafts are optionally
available:
1.5 times stronger than brass & aluminum
shaft compared to conventional TOCOS
shafts. Stainless shafts are ideal for hand-held
2-way radio to avoid accidental drop risks.
Variations of switches :
Either rotary or push-momentary types can
be optionally installed. Multifunction: On-off
switch function and band selector function
can be combined into one unit.
Sealed with O ring in between shaft and
bushing (Option): Waterproof meets with
IP67
A seal rubber is installed in between a
bushing and shaft to prevent water intrusion.
High torque models are optionally
available
Both vertical mount and horizontal types
are available.
Temp. range: Good in use in wide temp.
