9.0 <strong>Switch</strong> and Housing Model Codes<br />
<strong>Switch</strong><br />
Type<br />
The following charts identify the switch and housing model codes used with the buoyancy products. The<br />
eighth, ninth and tenth digit combinations may be used to identify the type and number of switches,<br />
number of contacts, switch magnet strength as well as housing type, size and options. The switch and<br />
housing codes in bold are currently valid and available in combination with various buoyancy products.<br />
The unbolded codes are no longer valid and should be replaced by the appropriate valid code. Mercury<br />
switches are no longer available. All mercury switch mechanisms should be replaced by dry contact<br />
mechanisms with the appropriate process temperature rating. See switch specifications, page 13.<br />
