MRW 10 Amp Solid State Switch MRW30, Model Shop Leeds

The 5 Way Multi Switch is intended for use with model boats for situation where you want to switch lots of items on and off and have a limited number of channels on your radio.

The unit can be operated in latching or non-latching mode, on any of the outputs.

Features

Failsafe if no signal when used on P.P.M radio systems.
The ON direction is selectable by the end user.
L.E.D indicator on the unit to show the on point.
Two units can operate on one channel when set to opposite directions.

Operating the unit

First it is recommend that set the channel you are using to operate the Standard Relay Switch to 100% travel, once this is done the Standard Relay Switch will switches on around 75% of the travel channel you are using.

Switch Direction

If you find the Solid State Switch is operating in the wrong direction for the switch channel you are using and channel reverse is not available on your radio or you are operating it with another device on that channel via a “Y” lead that needs to operate in a particular direction.

Then press and hold the key and switch your radio receiver on, this will reverse the action of the switch unit, carrying out the same operation will change it back again.

Hints & Tips

When using the switch with electric motors always fit suppression capacitors to stop contact arcing. If suppression is not fitted the life of the contacts will be much reduced. Where possible measure or work out the current of the load to be borne by the switcher, as the relay contact will only stand 10amps. Any switchers returned with burnt out contacts will be considered as damaged outside the warranty.

Wiring up

Because the Solid State Switch uses a power F.E.T to switch the load the polarity of the wiring is important. The black wire must always go to the negative of the supply you are using to operate the device you are switching on and off see diagram below

In general the switcher can be employed to switch lamps on and off, operate cameras with power wind, trigger flares and many other devices, when used with an electric motors a diode should be fitted across the motor to stop back EMF damaging the power F. E.T used to switch the load. Speciation
