Switches P and PT according to OST5R.8209-72

Switches P or PT are designed for switching electrical circuits (letter "T" indicates the presence of additional contacts and fuses).
Depending on the design and the number of connected lines, switches are made of the following types: P410, PT410, P418, PT418, P430, PT430, P436.
In this case:
a) the first digit after the letters denotes the maximum possible number of fixed positions of the switch handle (one position "off");
b) the last two digits - the number of switched lines.
The switches are designed for operation at the following values of active load voltages and currents:
Type of currentVoltage, not more than, VCurrent, not more than, A
AC 220 4
Direct 24 / 110 / 220 5 / 4,5 / 0,3
