MS Electronics TDS3 - Using Multiple Switches; Example 1: Parallel Wiring

Using Mulple Switches
To allow the connected load to be controlled from more than one locaon, mulple switches may
be connected, either in parallel, or using lower cost slave switches connected to a single master
switch.
Example 1: Parallel Wiring
Figure 3 illustrates a typical wiring arrangement using two TDS3 units; Figure 4 represents the same
conguraon as applied to a typical ceiling rose lighng circuit. This method can typically reuse pre-
exisng wiring from a 2-way switching installaon where 3-core cable has been run between the
switch locaons.
Each unit operates its own ming cycle, but the load is shared. When either unit (or both) is
acvated by its respecve touch-sensive buon, the load will switch on. Once both units have
med out, the load will switch o. Note that when holding the buon to cancel the meout, the
load will remain powered if the other unit is sll in the ‘ON’ state. For full control from any switch
locaon, see Example 2.

observed with relevance to the parcular installaon.
