| ASSOCIATED CONTROL SWITCHES & ACCESSORIES |
| DEFINITION | |
|
|
These switches are mechanical devices used to make and/or break one or more electrical circuits. They are designed to be solely operated by human hands. |
| OPERATION | |
| These switches have contact arrangements from one normally closed contact to a variable selector with up to five positions and twelve poles. Included in this section are the enclosures that will accept all of the switches on the previous pages. A "Die Safety Block Switch" is offered on page 38 which is normally used on presses with the removable switch key attached to a die safety block (Not Included). In order to place the die block in the die area the key must be removed from the switch thereby breaking and isolating the control circuit. Also included in this section are ring guards, legend plates and adapter plates etc. | |
| SELECTION | |
| The selection and use of a switch etc. involves knowing the details of the particular installation. The following rotary contact selector switches are offered with two positions, two poles or three positions, four poles or two position, Another style comes with two or four poles with a latch and provision for padlock security. Also, a custom order selector switch with or without a keylock is available. It can be produced in two through five positions and two through twelve poles. These are specials and require a factory quote. For the fastest service, complete the worksheet on page 39 and FAX it to our Customer Service department at 219-495-2186. The palm switch guard/actuator is available to reduce the operating force of the palm buttons. There are two advantages to this device. First of all, there is a mechanical advantage which means it takes less external force to actuate the switch it is mounted to. Secondly, the hand contact area is very large (approx. 20 sq. in.) which dissipates the pushing force into a much lower psi. |
| INSTALLATION | ||||||
Every installation is unique, therefore there are only a very few hard
and fast rules to follow.
Above all, observe all safety requirements,
procedures, and local codes.
To mount these devices it will be necessary
to have a suitable mounting enclosure.
These are available from REES
(see page 41).
If the switch is to be mounted on a larger enclosure the
required switch mounting information can be found with the dimensional
drawings at the end of this section.
On pages 38 through 43 you will
find many different items that should satisfy any installation
requirements.
At the end of this section of this catalog you can find a
number of accessory items to facilitate in the installation of these
devices.
All mechanical devices, these units included, will wear out and
eventually need to be replaced.
The estimated minimum mechanical life is
500,000 operations.
Regular scheduled preventative maintenance
inspections are strongly recommended.
Some conditions to look for are :
Physical damage to the device |
