Murata 10uf 0603 LOW ESR SMD Capacitor 0.25W 4.8mm Clear StrawHat Cool White LED This Single Pole Double Throw

This Single Pole Double Throw (SPDT) is a micro switch that needs less force to operate

Rather than that heat shrink sheet provides electrical insulation

It's not too costly

one of which is connected to an IR LED and the other to a phototransistor

6V DC Anode Forward Current 150mA DC Gate Current 50mA Non-Repetitive Peak Forward Current 5A Operating Temperature -50°~100°C Power dissipation 300mW
